There is probably a spectrum of people with different wants in this regard. Alt effects could have a slider type setting. setting 1, just normal lootable items appear. setting 2 all containers and non-secret interactables. Setting 3, display everything.
Still seems strange it isn't in already, in some variation or other. Same thing with esc button not closing conversations-- why doesn't it? It's especially annoying when NPC has many choices and you need to scroll down for the conversation exit button.
